Abstract:

When a vertical oil storage tank is on fire, the tank wall is directly exposed to the flame, causing rapid temperature rise and a sharp decrease in strength. The load-bearing capacity of the steel plate is severely impaired, so the reasonable design of fire cooling water system is very important. This paper focuses on fixed fire cooling water system for vertical oil storage tanks. By optimizing design parameters, nozzle selection and layout schemes, the safety of oil storage tanks has been enhanced, fire risks have been reduced, and engineering cost control has been taken into account. This provides a reference for similar engineering designs.
